Coloradoâs Scenic Million Dollar Highway: Silverton to Ouray. The scenic drive on Coloradoâs Million Dollar Highway (U.S. Route 550), from Silverton to Ouray, just might be the most eye-popping, awe-inspiring drive we have ever taken.
We've done the Million Dollar Highway trip twice and will be taking the Durango & Silverton RR next month for the second time in two years. Well worth the price. The mileage from Ouray to Silverton is 24 miles, not 12, but every mile is a treasure, and Box Canyon in Ouray is a real must see place.
